[0004] In order to reduce the proportion of black belly traits in chicken flocks and improve the appearance of broiler carcasses on the market, it is hoped to find an early selection method to reduce the proportion of black belly traits in chicken flocks, but there are no reports of such methods so far

Embodiment 1

[0049] Example 1: Correlation analysis between the measured value of the peritoneal color phenotype of the local chicken breed - Huiyang bearded chicken and the observed value of the peritoneal color phenotype of the market-aged carcass

[0050] According to the above-mentioned phenotypic determination method of chicken peritoneal melanin deposition, a total of 446 Huiyang bearded chickens (Huiyang bearded chickens were purchased from Guangdong Academy of Agricultural Sciences) were collected from 2 batches of 446 chickens (248 chickens in the first batch and 198 chickens in the second batch). Scientific Research Institute) at the age of 3 weeks and 6 weeks to measure and grade the melanin phenotype in vivo, and record the phenotype of the peritoneal melanin deposition degree in living chickens. The chickens were slaughtered at the age of 16 weeks, and the peritoneum was exposed by cutting the skin of the abdomen of the naked chicken after shedding. The degree of peritoneal mel...

Abstract

The invention discloses a black peritoneal phenotype determination method for chicken early selection and application thereof. The method comprises the following steps: (1) pluck the coat from the end of the keel of a chicken aged 3 to 6 weeks to the area below the anus where the skin layer is thin and there is no obvious muscle layer to cover, including the two sides to the last rib and the edge of the pubic bone. , as the judgment area; (2) observe the judgment area, and determine the phenotype of the chicken peritoneal melanin deposition according to the chicken peritoneal melanin deposition status; wherein, the chicken peritoneal melanin deposition status is divided into 4 grades of 0 to 3. The method of the present invention can measure the phenotype of peritoneal melanin deposition degree in early live chicken flocks and select and retain it, and then achieve the purpose of reducing the proportion of black-bellied phenotypes in market-aged flocks, and provide early breeding work for broiler carcass traits. The necessary method can save the breeding cost and improve the economic benefit.

Description

technical field [0001] The invention relates to the technical field of poultry breeding and breeding, in particular to a black peritoneal phenotype determination method for chicken early selection and application thereof. Background technique [0002] In my country, broiler chicken production is dominated by white-feather broiler chickens and yellow-feather broiler chickens. After more than 20 years of development, yellow-feather broiler chickens have now occupied nearly half of my country's broiler chicken market, and are varieties with independent intellectual property rights in my country. [0003] In recent years, incidents of human infection with H7N9 influenza have occurred from time to time, causing heavy losses to the yellow-feather broiler industry that relies heavily on live poultry trading, exposing the shortcomings of the traditional live poultry trading model, forcing industrial transformation, and objectively promoting the yellow-feather broiler industry. The p...
